EP Series Resonance Free Variable Frequency and Eccentric Moment Vibro Hammer

Product Performance

EP Series Resonance Free Variable Frequency and Eccentric Moment Vibro Hammer is a new series of products jointly developed by our company, Beijing Institute of Construction Mechanization and Japan Construction Engineering Co., Ltd. This series of products has won the first prize of scientific and technological progress of the Ministry of Construction, and is listed as a guide project for the promotion and transformation of scientific and technological achievements of the Ministry of Construction; exported to Japan, it is known as the "new era pile hammer", and the Ministry of Construction of Japan (now the Ministry of Land, Infrastructure, Transport and Tourism) has approved this series of models Tested and evaluated, and listed as a product for the promotion and use of new technologies.

The mechanism of EP series electric drive vibrating pile hammer is characterized by the use of hydraulic control eccentricity conversion device, which can realize "zero" start, "zero" stop and stepless adjustment of the eccentric torque during operation.Compared with the traditional vibrating pile hammer, it shows great advantages.

◆Reduce starting energy consumption Realize starting under the condition of no eccentric moment, which solves the problem that the widely used vibrating pile hammer starts with eccentric moment and needs a large-capacity power supply	◆"Zero" startup, "zero" shutdown Realize "zero" start and "zero" stop, overcome the resonance generated when starting and stopping with eccentric moment, and prevent the occurrence of noise caused by resonance and damage to other equipment parts
◆Stepless adjustment of eccentric moment The eccentric moment can be adjusted conveniently and freely during the operation of the machine to adapt to the pile sinking and pulling requirements of different soil layers, so as to achieve the ideal pile sinking and pulling speed and efficiency	◆Low center of gravity, good stability The exciter of the large-scale vibrating pile hammer adopts a horizontal structure, the center of gravity of the whole machine is low, and the stability is good. It is equipped with a beam type vibration reduction system, which greatly reduces the height of the whole machine

Application Scope

Vibration sinking prefabricated engineering piles (steel pipe piles, concrete piles), cast-in-place pile construction, can also be applied to the construction of temporary support piles (steel pipes, steel plates) for sinking and pulling, as well as foundation improvement projects. Combined with the double casing construction method, it can be applied to the construction of boreholes, planting piles, etc
